WATER-Moron.

Specification of Letters Patent.

Application filed November 21, 1904. Serial No. 233,664@

motive power of a body `of water iiowing through a main or conducting pipe, an ob .iect which I attain by the mechanism which I will now proceed to describe, reference b eing had to the accompanying drawing, in

Figure 1 is a plan of a portion oi a water main with two ol my iniproved niotors connected thereto, with the cover of one being removed to display he power devices therein; and Fig. 2 is a cross section taken on lin of Fig. 1.

The numeral 2 represents a pipe line or water main having a gate orlike valve 3 and openings upon each side of the latter which are connected by branch, pipes 4 and d with the inlet andoutlet openings 5 and 6, respectively, of the motor casing or casings 7 and forming therewith a by-pass wherethrough .the water is conveyed back to the niain,

Valves 8 are included. in these branch pipes ,for the purpose of shutting off the water from Ithe motors.

In the drawings I show two motors con- ;nected together but it should be understood `that one or more can be used according to the power required and the force of the water.

The nfotor-casings are. eachprovided with two arallel transversely arranged chambers 9 an 10 which are connected at their ends to ,each other by reverse channels 11 and interiediately of their lengths to said casing openings. These channels and chambers are circular in cross section and extending axially through the latter are power-shafts 12 and 12 severally carrying a right-hand screw 13 'and a, left-hand screw 13. The spiral blades cured to their respective shafts.

of these screws are formed integral with hubs 14 which are keyed or otherwise rigidly se- For convenience in manufacturing und assembling the artsof the motor, the casings are each divi ed into two parts on a horiand are secured together by bolts, not shown. 15 are o"lands which project into semi-cylin drical depressions 15 oi' the casing to form stuffing boxes to prevent the leakage of the water where the said shafts extend through the casing. Journal boxes 16 are provided for the shafts yand the power can be taken by 'suitable means, such as pulleys, directly from the latter or from sup leinental shafts 17 and 18 which are actuated -by trains of gears 19 and 20, as is usual in transmitting power. The o eration of the invention is as follows: Vlihen the valve 'in the main is closed and those vin the branch pipes opened, the water will b'e diverted to'pass through the motors Upon entering the first motor, where more than one is used as in the illusj tration, the stream is bifurcated and each halt` is caused to ilow in opposite directions thence back to the casing outlet where it is united in a single body, to be again divided and returned to the-same condition in each motor used. The divided streams of water act againstI the right and left-handed spiral blades of each sliaibt and rotate thesame with the end pressures balanced thereby requiring no collars or thrust boxes to prevent endwise motion. v

It' may be said that the several ower shafts may just as well be used indivi nelly for transmitting ower, for oftentimes it is advantageous to il mit the accumulated force integrally.l

Having described my invention, what I claini as new and desire to secure by Letters- Patent, is

In a device of the class described, the combination with a water main of an elongated casing having inlet and discharge passages at its opposite sides and divided centrally by a longitudinal partition spaced at the ends from the casino' and with bearings extending laterall f thereirorn, conduits leadin at two oints ibi-om said main and connecte respectively to the discharge and intake passages of said casing regulating valves positioned in each of said conduits, shafts spaced apart and journaled through said casing at opiposite sides of said partitiony and supporte in said bearings, each shaft/carrying an integral right hand screw an an integral left and operating in said casing, and a supportzontal plane-passing through the shafts axes` land screw at opposite sides of said partition o so ratherthan to transf L v .ing-framework surroundin said easing,"v the `ranged Within a. c'onnnoswater passage', als
